The volume of a cylinder with a radius r and a height h:
The volume of a cone with a radius r and a height h:
Therefore
We have
Substitute:
Answer: The volume of a cone is equal 10.75 in³
Answer:
The equation is
The slope is m=-4
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to
where
y is the amount left in the saving account
x is the number of weeks
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value
In this problem we have
The slope is equal to
--> is negative because is a decreasing function
The y-intercept or initial value is
substitute
R = 7 d = 14 (to find the radius d ÷ 2) h = 10
(2πr²)
2 x 3.14 x (7x7)
2 x 3.14 x 49 = 307.72
(πdh)
3.14 x 14 x 10 = 439.6
Take the two answers and add.
307.72 + 439.6
Final answer = 747.32
We can factor this using the AC method.
We can split the middle term using the factors 4 and -9
x^2 + 4x - 9x - 36
Factor by grouping.
x(x + 4) - 9(x + 4)
<h3><u>(x - 9)(x + 4) are the factors of this polynomial.</u></h3>
